大黄素、大黄酸和芦荟大黄素对金黄色葡萄球菌和甲型链球菌有较强的抑制作用。大黄酸、大黄素、大黄素醇、大黄素酸和芦荟大黄素对NADH脱氢酶有不同程度的抑制作用,其中以大黄酸和大黄素作用最强,IC_(50)分别为31.5和48.8μg/ml,大黄酚和大黄素甲醚则无明显作用。大黄素、大黄素醇、大黄素甲醚、大黄素酸和大黄酸对NADH氧化酶有明显的抑制作用,其中以大黄素作用最强,IC_(50)为1.2μg/ml,芦荟大黄素和大黄酚则不明显。大黄素对琥珀酸脱氢酶和琥珀酸氧化酶有明显的抑制作用,IC_(50)分别为60和15.3μg/ml。 Emodin, rhein and aloe-emodin have a strong inhibitory effect on Staphylococcus aureus and Streptococcus aureus. Rhein, emodin, emodin, dhs, and aloe-emodin have different degrees of inhibition on NADH dehydrogenase, among which rhein and emodin are the most effective, IC 50 is 31.5 and 48.8 μg, respectively. /ml, chrysophanol and rhubarb have no significant effect. Emodin, emodin, rhein, dhs, and rhein had significant inhibitory effects on NADH oxidase, with emodin acting most strongly, IC 50 being 1.2 μg/ml, aloe-emodin and Chrysophanol is not obvious. Emodin significantly inhibited succinate dehydrogenase and succinate oxidase, and IC 50 was 60 and 15.3 μg/ml, respectively.
